Only 2 hours? It depends what you started out with. Was it a kit or did you produce it yourself? Is it a 3D print job, and did you do the drawings? It's amazing to get that accuracy at such a scale. Well done.

Hi allAs Doug says It is a kit from T Gauge .They have a Yellow and orange crane to reproduce .

got some time off this weekend so I have got the yellow version to do this time and I will now build it better as the cab clear parts seem to slide away from you and you have to glue seperetly in order to get it right.

Will place a seating figure in the cab on my second crane.

Hope they bring out more versions of other buildings to be built either in kit form or ready made?
